Despite being the member of the international disarmament and non-proliferation conventions i.e. Non-Proliferation Treaty (NPT), Chemical Weapons Convention (CWC) and Biological Weapons Convention (BWC) which include their own specific export control regimes, some developed countries established parallel export control regimes that are against their commitments under aforementioned international instruments. These ad-hoc regimes are not open to all members of international community. These regimes would have always been used as a political leverage against targeted states by imposing restrictions and sanctions against them. They restrict the transfer of dual use equipment and materials and high-technology and know-how to targeted states that negatively affect their development process.
